Anyone with advice on the ME3400 which some telcos use for Metro Ethernet Forum (MEF) services? Specifically looking for layer2 vs layer 3. At Layer 2 NNI/UNI vs dot1q qinq vs private VLANs. At Layer 3 multiple VRF CE/PE support. Specifically which connectivity options have been found to be most reliable and scalable. ________________________________ This communication, together with any attachments or embedded links, is for the sole use of the intended recipient(s) and may contain information that is confidential or legally protected.
